The electric field mill applied in the preventive lightning protection measures the atmospheric electric field. From the changes of this field lightning activity can be estimated.

However a noise appears with the precipitation, which can influence the results.

My BSc. thesis examines the effect of this precipitation noise for the electric field mill’s measurement results.

First I give a short overview about the lightning detection systems and the preventive lightning protection, then a I write a few words about the electric field mill.

The phenomenon is reviewed by the international literature.

With the use of the department’s electric field mill I have created an experiment to find out, what effect has the precipitation noise for the measurement results.

I have created a simple computational model with the help of MATLAB, and made calculations about the relationship between the electric field and precipitation.

In the knowledge of the results I have suggested a recommendation of a solution idea.
